  Message : Add feature flags to EGLPlatformParameters "tie". The missing flags were causing the configs to be reused and improperly tested. Noticed when working with the Vulkan command graph feature. Bug: angleproject:4029 Change-Id: I2fea73fc0637d1adbf73577eb5dfcfa4a759c066 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2019503 Reviewed-by: Jamie Madill <jmadill@chromium.org> Reviewed-by: Michael Spang <spang@chromium.org> Commit-Queue: Jamie Madill <jmadill@chromium.org>
